I have tons of tiny white starfish in my salt water tank. They came in on live rocks. Are they good or bad?

Answer 1

It really depends on the type but they sound like asternia starfish and they can be ones that you want to avoid to me as they will eat small polyps.

Answer 2

The star fish are called sand sifters. They are actually very beneficial to the tank. Depending on how big of a tank you have. You could take back some of the stars to the store you bought the live rock from, and resell the stars to them.

Answer 3

It depends on how big your tank is, what you have in it, etc. They are like snails; they'll keep your things in the tank clear of algae and junk, but they will over populate everything else. Keep them to a minimum, if at all possible. Or, get some type of fish that will eat them. They wont eat them all, just enough to keep from over-crowding the tank. GOOD LUCK!!

Answer 4

The Quran mentions 'barzakh' meaning a barrier. It separates salt water from candy water. The 'Barzakh' is quite now no longer a barrier . it rather is in fact the alternative . The waters are no longer any longer forbidden to tresspass. candy water flowing from the rivers and salt water do now no longer combination in the reducing-part yet finally they combination. it rather is like as quickly as you pour milk in a cup of coffee they do now no longer combination at as in the present day as yet as quickly as you stir them they combination.

Answer 5

I used to get them too. They were harmless, but kind of fun to look at!

Answer 6

they are fine , most of them wont survive once you do a partial water change.

Answer 7

if they wear white hats, they're good... if black ones, they're bad!
